如何在詹金斯管道中仅获取当前阶段的控制台输出？

正在尝试获取jenkins管道中当前阶段的控制台输出。我的最终目标是存储此输出，直到构建发布步骤为止，然后通过不和谐通知发出该输出。

   ```js

stage("Build Javadoc") { steps { script { try { sh script: "cd ${params.PLUGIN} && /opt/gradle/bin/gradle atherysdoc" } catch (Exception e) { exception = e; failureReason = // Get current stage console output? throw e; } } } }

      ```js
failure {
            discordSend webhookURL: "https://discordapp.com/api/webhooks/blahblah",
                        title: "Build Failure: ${fullPluginName}",
                        successful: false,
                        result: 'FAILURE',
                        link: env.BUILD_URL,
                        description: "${exception}\n```${failureReason}```"
        }

我想要这个的原因是因为仅发出失败的shell命令的异常是结果为hudson.AbortException: script returned exit code 1，这不是很有帮助
